Yabba

Yabba adds barrels that can only hold one type of item but the capacity is incredibly large and can be upgraded to hold an infinite amount.

The barrels can be customized to be a variety of shapes with the hammer tool and can take on the appearance of any block with the painter tool.

The upgrades are tiered and must be applied in order from iron to emerald.

And the wrench can rotate the barrels if you need them facing a different direction.

They are stackable and because of the high capacities and varying depths they can come in handy to store those items like dirt and cobblestone that may just take up too many chests that could otherwise contain more important items. This mod also requires an additional API found here.
